What is SMTP relay, and why do you need it to send large amounts of email?

There’s a lot going on behind the scenes in a transactional email to make sure your emails get delivered and recipients get your most essential communications on time. One protocol that helps with this is SMTP.

 

But what exactly are SMTP relays, and how do they enter into the picture? We’ll go through how SMTP relay servers make sure your messages reach from point A to point B (and everything in between!) in this article. Ready? 

 

Let’s get started!

 

What is an SMTP relay?

 

An SMTP relay is an email service that transmits large amounts of email messages through SMTP servers to avoid being filtered as spam.

 

Simple Mail Transfer Protocol (SMTP) is an acronym for Simple Mail Transfer Protocol. SMTP is an industry-standard for routing large amounts of email messages through SMTP servers in order to send, receive, and relay emails over the Internet.

 

The zig-zag procedure of transmitting an email from one email server to another until it reaches the destination is known as a relay or mail relay.

 

What is an SMTP relay and how does it work?

 

Before reaching your recipient’s inbox, an email must travel a circuitous journey and leap through a few hoops.

Your email is transmitted to your server’s Mail Submission Agent when you click “send” in your email app or Mail User Agent (MUA) (MSA). Before sending your email to a Mail Transfer Agent, it double-checks it for accuracy, including missing “To” fields (MTA).

 

The MTA checks the recipient’s domain’s Mail Exchange (MX) records. This instructs the email to send to the appropriate server. Before being approved by a Mail Delivery Agent, your email travels this path and is transmitted to another MTA (MDA).

 

Your email is received by the MDA, which changes it to a readable format before passing it on to the recipient’s MUA. Your email will ultimately emerge in the inbox of the recipient’s email app after this lengthy voyage (which takes only seconds!).
